shouldn't there be four parameters? I'm a little confused here, I know these facts are tedious at best, but I'd sure appreciate the help

please elder?

Grippy, the PCM only has one pin 'confirmed' available for the fans. This only gives you one set of turn on and turn off temps. With another harness soon to be available, there is an adjustable low speed side on an external control box and the normal PCM adjustments. The low speed would come on with the temp setting from the external controler OR the AC, leaving the high speed for the PCM to turn on.
